‘72 brake line jumper

I have those the other end looks like a mushroom not the regular flare that you are showing in your pic, Correct? Those were on 10x2 cast iron drums also called taxi cab drums. They were only available from the dealership which is why i bought 2 extra sets.

Yeah that's right. I'm not sure why the different shape is necessary... or maybe the shape of the wheel cylinder just mushroomed the flange out when it was tightened.

I ended up just buying the parts from right stuff. Hated to pay $10 for shipping but I'd rather not have to deal with shaping a six inch line.

Thanks for the help!
